Maintenance and service
5.2 Replacing modules (spare part scenario)
Automatic upgrading/downgrading (FW update)
When starting up, the system automatically upgrades or downgrades all DRIVE-CLiQ
components to the version of the component firmware on the CompactFlash Card.
Components that cannot be downgraded to the component firmware version on the
CompactFlash Card (for example, old firmware on the CompactFlash Card and new
components to which the old firmware cannot be loaded) retain their firmware version. The
resulting firmware version combinations are always functional.
Note
During an automatic FW update, please take note of the messages and alarms in the
SIMOTION SCOUT detail window.
An FW update on the D410 is signaled by the RDY LED flashing yellow, while on the DRIVE-
CLiQ components (TM, SMC, etc.) it is signaled by the RDY LED flashing red/green.
• FW update running: RDY LED flashes slowly (0.5 Hz)
• FW update complete: RDY LED flashes quickly (2 Hz)
Go offline once all the FW updates are complete, then switch the 24 V supply for the
upgraded/downgraded initialization components off/on.
The update function can be deactivated using CU parameter p7826 in the expert list.
